Is there a way to sort shape keys by name?
On the "Object Data" tab in the "Shape Keys" panel; click the tiny + symbol at the lower left of the shape key list.



This will enable the filtering and sorting options



Clicking the AZ button sorts the list alphabetically.

(The tooltip lists the relevant python command as MESH_UL_shape_keys.use_filter_sort_alpha)

These filtering options/sorting options are hidden away in all (most?) of these lists.
